SAFEtY<br />
WARNING!<br />
When using the machine, approved personal protective equipment (shown in illustrations)<br />
shall be used. Personal protective equipment cannot eliminate the risk of injury but it will<br />
reduce the degree of injury if an accident does happen. Ask your retailer for help in choosing<br />
the right equipment.<br />
Slope Operation<br />
Slopes are a major factor related to loss of control and<br />
tip-over accidents, which can result in severe injury or<br />
death. Operation on all slopes requires extra caution. If<br />
you cannot back up the slope or if you feel uneasy on<br />
it, do not mow it.<br />
• Mow up and down slopes (10 degrees maximum),<br />
not across.<br />
• Watch for holes, ruts, bumps, rocks, or other<br />
hidden objects. Uneven terrain could over<strong>turn</strong> the<br />
machine. tall grass can hide obstacles.<br />
• Choose a low ground speed so that you will not<br />
have to stop while on the slope.<br />
• Do not mow on wet grass. tires may lose traction.<br />
• Avoid starting, stopping, or <strong>turn</strong>ing on a slope. If<br />
the tires lose traction, disengage the blades and<br />
proceed slowly straight down the slope.<br />
• Keep movement on the slopes slow and gradual.<br />
Do not make sudden changes in speed or<br />
direction, which could cause machine to roll over.<br />
• Use extra care while operating machine with grass<br />
catchers or other attachments; they can affect the<br />
stability of the machine.<br />
Personal protective equipment<br />
Mow up and down, not side to side<br />

Do not use on steep slopes.<br />
Do not try to stabilize the machine by putting your<br />
foot on the ground.<br />
Do not mow near drop-offs, ditches, or<br />
embankments. the machine could suddenly roll<br />
over if a wheel is over the edge or if the edge<br />
caves in.<br />
Children<br />
tragic accidents can occur if the operator is not alert to<br />
the presence of children. Children are often attracted<br />
to the machine and the mowing activity. Never assume<br />
that children will remain where you last saw them.<br />
• Keep children out of the mowing area and in the<br />
watchful care of a responsible adult other than the<br />
operator.<br />
• Be alert and <strong>turn</strong> machine off if a child enters the<br />
area.<br />
• Before and while backing, look behind and down<br />
for small children.<br />
• Never carry children, even with the blades shut<br />
off. they may fall off and be seriously injured or<br />
interfere with safe machine operation. Children<br />
who have been given rides in the past may<br />
suddenly appear in the mowing area for another<br />
ride and be run over or backed over by the<br />
machine.<br />
• Never allow children to operate the machine.<br />
• Use extra care when approaching blind corners,<br />
shrubs, trees, or other objects that may block your<br />
view of a child.<br />

Safe Handling of Gasoline<br />
to avoid personal injury or property damage, use<br />
extreme care in handling gasoline. Gasoline is<br />
extremely flammable and the vapors are explosive.<br />
• Extinguish all cigarettes, cigars, pipes, and other<br />
sources of ignition.<br />
• Use only approved gasoline container.<br />
• Never remove gas cap or add fuel with the engine<br />
running. Allow engine to cool at least two (2)<br />
minutes before refueling.<br />
• Never fuel the machine indoors.<br />
• Never store the machine or fuel container where<br />
there is an open flame, spark, or pilot light such as<br />
on a water heater or other appliance.<br />
• Before you begin refueling, minimize the risk of<br />
static electricity by touching a metal surface.<br />
• Never fill containers inside a vehicle or on a<br />
truck or trailer bed with plastic liner. Always place<br />
containers on the ground away fr<strong>om</strong> the vehicle<br />
when filling.<br />
• Remove gas-powered equipment fr<strong>om</strong> the truck<br />
or trailer and refuel it on the ground. If this is not<br />
possible, refuel such equipment with a portable<br />
container, rather than fr<strong>om</strong> a gasoline dispenser<br />
nozzle.<br />
• Keep the nozzle in contact with the rim of the fuel<br />
tank or container opening at all times until fueling<br />
is c<strong>om</strong>plete. Do not use a nozzle lock-open device.<br />
• If fuel is spilled on clothing, change clothing<br />
immediately.<br />
• Never overfill fuel tank. Replace gas cap and<br />
tighten securely.<br />
• Do not start the engine near spilled fuel.<br />
• Never use gasoline as a cleaning agent.<br />
• If leaks arise in fuel system, engine must not be<br />
started until problem has been resolved.<br />
• Check the fuel level before each use and leave<br />
space for the fuel to expand, as the heat fr<strong>om</strong> the<br />
engine and the sun may otherwise cause the fuel<br />
to expand and overflow.<br />
SAFEtY<br />
WARNING!<br />
The engine must not be started when the driver’s floor plate or any protective plate for the<br />
mower deck’s drive belt is removed.<br />

Steering Control Levers<br />
the machine’s speed and direction are continuously<br />
variable using the two steering controls. the steering<br />
controls can be moved forward or backward about<br />
a neutral position. Furthermore, there is a neutral<br />
position, which is locked if the steering controls are<br />
moved outward.<br />
When both controls are in the neutral position (N), the<br />
machine stands still.<br />
By moving both controls an equal amount forward<br />
or backward, the machine moves in a straight line<br />
forward or backward respectively.<br />
In order, for example, to <strong>turn</strong> right while moving<br />
forward, move the right control towards the neutral<br />
position. the rotation of the right wheel is reduced and<br />
the machine <strong>turn</strong>s to the right.<br />
Zero <strong>turn</strong> can be achieved by moving one control<br />
backward (behind the neutral position) and carefully<br />
moving the other steering control forward fr<strong>om</strong> its<br />
neutral position. the rotation direction when <strong>zero</strong><br />
<strong>turn</strong>ing is determined by which steering control is<br />
moved backward behind the neutral position. If the left<br />
steering control is pulled backward, the machine <strong>turn</strong>s<br />
to the left. Use extra care when using this maneuver.<br />
If the steering controls are in uneven positions when<br />
standing still or do not fit in the slots for moving the<br />
controls outward, they can be adjusted.<br />

Refueling<br />
Read the safety instructions before refueling. the<br />
machine has one fuel tank, just behind the seat. the<br />
tank volume is 3 gallons (11.4 liters).<br />
Make sure the fuel caps are properly tightened and the<br />
cap gasket is not damaged.<br />
the engine will run on a minimum of 85-octane<br />
unleaded gasoline (no oil mix). Environmentally<br />
adapted alkylate gasoline can be used. See also<br />
technical Data concerning ethanol fuel. Methanol fuel<br />
is not allowed. Do not use E85 alcohol based fuel.<br />
Damage to engine and c<strong>om</strong>ponents may occur.<br />
20 - HUSQVARNA<br />
WARNING!<br />
Gasoline is highly flammable. Observe<br />
caution and fill the tank outdoors (see<br />
the safety instruction).<br />
IMPORTANT INFORMATION<br />
Experience indicates that alcohol blended<br />
fuels (called gasohol, ethanol or methanol)<br />
can attract moisture which leads to separation<br />
and formation of acids during storage. Acidic<br />
gas can damage the fuel system of an engine<br />
while in storage. To avoid engine problems,<br />
the fuel system should be emptied before<br />
storage of 30 days or longer. Drain the gas<br />
tank, start the engine and let it run until the<br />
fuel lines and carburetor are empty. Use fresh<br />
fuel the next season. See Storage Instructions<br />
for additional information. Never use engine<br />
or carburetor cleaners in the fuel tank or<br />
permanent damage may occur.<br />

Read “Safety Instructions” section and following<br />
pages, if you are unfamiliar with the machine.<br />
Training<br />
Zero <strong>turn</strong> mowers are far more maneuverable than<br />
typical riding mowers due to their unique steering<br />
capabilities.<br />
We suggest that this section be reviewed in its entirety<br />
prior to attempting to move the mower under its own<br />
power. Additionally, we suggest when first operating<br />
the mower, use a reduced throttle speed and reduced<br />
ground speed by NOt moving control levers to the<br />
furthest forward or reverse positions during initial<br />
operation, or until operator bec<strong>om</strong>es c<strong>om</strong>fortable with<br />
controls. We also suggest first time users, or new<br />
users to Zero <strong>turn</strong> mowers to bec<strong>om</strong>e familiar with<br />
the mower’s movement on a hard surface, such as<br />
concrete or blacktop PRIOR to attempting to operate<br />
on turf. Until operator bec<strong>om</strong>es c<strong>om</strong>fortable with<br />
mower controls and <strong>zero</strong> <strong>turn</strong>ing capability, they may<br />
damage turf due to overly aggressive maneuvers.<br />
IMPORTANT INFORMATION<br />
When control levers are in the reverse position<br />
they re<strong>turn</strong> to neutral when released. This may<br />
cause the mower to suddenly stop.<br />
OPERAtION<br />
Steering<br />
To move forward and backward<br />
the direction and speed of the mower’s movements<br />
is effected by the movement of the control lever(s)<br />
on each side of mower. the left control lever controls<br />
the left wheel. the right control lever controls the right<br />
wheel.<br />
First time users should push mower (see “Moving by<br />
Hand” in the Operation section) to an open, flat area,<br />
without other people or vehicles/obstacles nearby. In<br />
order to move unit under its own power, the operator<br />
must be in the seat, start engine (see “Before Starting”<br />
in Operation section), adjust engine speed to idle,<br />
disengage parking brake, do not engage blades at<br />
this time, rotate control levers inward. As long as<br />
the control levers have not been moved forward or<br />
backwards, mower will not move. Slowly move both<br />
control levers forward slightly. this will allow mower<br />
to start moving forward in a straight line. Pull back on<br />
control levers to the neutral position and mower should<br />
stop moving. Pull back slightly on control levers, this<br />
will allow mower to start moving backwards. Push<br />
forward on control levers to the neutral position and<br />
mower should stop moving.<br />
To <strong>turn</strong> to the right<br />
While moving in a forward direction, pull the right lever<br />
back towards the neutral position while maintaining the<br />
position of the left lever, this will slow the rotation of<br />
the right wheel and cause the machine to <strong>turn</strong> in that<br />
direction.<br />
To <strong>turn</strong> to the left<br />
While moving in a forward direction pull the left lever<br />
back towards the neutral position while maintaining<br />
the position of the right lever, this will slow the rotation<br />
of the left wheel and cause the machine to <strong>turn</strong> in that<br />
direction.<br />
To <strong>zero</strong> <strong>turn</strong><br />
While moving in a forward direction, first pull both<br />
control levers back until the mower stops or slows<br />
dramatically.<br />
then by alternating one lever slightly to the forward<br />
position and the other in the reverse position.<br />

Mowing Tips<br />
• Observe and flag rocks and other fixed objects to<br />
avoid collisions.<br />
• Begin with a high cutting height and reduce it until<br />
the desired mowing result is attained.<br />
the average lawn should be cut to<br />
2½" (64 mm) during the cool season and over 3"<br />
(76 mm) during the hot months. For healthier and<br />
better looking lawns, mow often after moderate<br />
growth.<br />
For best cutting performance, grass over 6" (15<br />
cm) in height should be mowed twice. Make the<br />
first cut relatively high, the second to the desired<br />
height.<br />
• the mowing result will be best with a high engine<br />
speed (the blades rotate rapidly) and low speed<br />
(the rider moves slowly). If the grass is not<br />
too long and dense, the driving speed can be<br />
increased without negatively affecting the mowing<br />
result.<br />
• The finest lawns are obtained by mowing often.<br />
the lawn bec<strong>om</strong>es more even and the grass<br />
clippings more evenly distributed over the mown<br />
area. the total time taken is not increased as a<br />
higher operating speed can be used without poor<br />
mowing results.<br />
• Avoid mowing wet lawns. the mowing result is<br />
poorer because the wheels sink into the soft lawn,<br />
clumps build, and the grass clippings fasten under<br />
the cowling.<br />
• Hose the mower deck underside with water after<br />
each use. When cleaning, the mower deck shall<br />
be raised into the transport position. Make sure the<br />
mower is cooled and the engine is off.<br />
• Use c<strong>om</strong>pressed air to clean top surface of the<br />
deck. Avoid flooding water on top surface, engine<br />
and electrical c<strong>om</strong>ponents.<br />
• When the mulching kit is used, it is important that<br />
the mowing interval is frequent.<br />

Oil Rec<strong>om</strong>mendations<br />
Using the proper type and weight of oil in the<br />
crankcase is extremely important. So is checking oil<br />
daily and changing oil regularly. Failure to use the<br />
correct oil, or using dirty oil, causes premature engine<br />
wear and failure.<br />
Use high quality detergent oil of API (American<br />
Petroleum Institute) service class SG, SH, SJ<br />
or higher. Select the viscosity based on the air<br />
temperature at the time of operation.<br />
IMPORTANT INFORMATION<br />
Using other than service class SG, SH, SJ or<br />
higher oil or extending oil change intervals<br />
longer than rec<strong>om</strong>mended can cause engine<br />
damage.<br />
IMPORTANT INFORMATION<br />
Synthetic oils meeting the listed classifications<br />
may be used with oil changes performed<br />
at the rec<strong>om</strong>mended intervals. However to<br />
allow piston rings to properly seat, a new or<br />
rebuilt engine should be operated for at least<br />
50 hours using standard petroleum based oil<br />
before switching to synthetic oil.<br />
A logo or symbol on oil containers identifies the API<br />

Winter Storage<br />
At the end of the mowing season, the machine should<br />
be readied for storage (or if it will not be in use for<br />
longer than 30 days). Fuel allowed to stand for long<br />
periods of time (30 days or more) can leave sticky<br />
residues that can plug the carburetor and disrupt<br />
engine function.<br />
Fuel stabilizers are an acceptable option as regards to<br />
the sticky residues that can occur during storage.<br />
Add stabilizer to the fuel in the tank or in the storage<br />
container. Always use the mixing ratios specified by<br />
the manufacturer of the stabilizer. Run the engine for<br />
at least 10 minutes after adding the stabilizer so that it<br />
reaches the carburetor. Do not empty the fuel tank and<br />
the carburetor if you have added stabilizer<br />
WARNING!<br />
Never store an engine with fuel in the<br />
tank indoors or in poorly ventilated<br />
spaces where fuel vapor can c<strong>om</strong>e in<br />
contact with open flames, sparks, or a<br />
pilot light such as in a boiler, hot water<br />
tank, clothes drier, etc. Handle the fuel<br />
with care. It is very flammable and<br />
can cause serious personal injury and<br />
property damage. Drain the fuel into<br />
an approved container outdoors and<br />
far away fr<strong>om</strong> open flame. Never use<br />
gasoline for cleaning. Use a degreaser<br />
and warm water instead.<br />
StORAGE<br />
to ready the machine for storage, follow these steps:<br />
1. thoroughly clean the machine, especially under<br />
the mower deck. touch up damage to the paint<br />
and spray a thin layer of oil on the underside of the<br />
mower deck to avoid corrosion.<br />
2. Inspect the machine for worn or damaged parts<br />
and tighten any nuts or screws that may have<br />
bec<strong>om</strong>e loose.<br />
3. Change the engine oil; dispose of properly.<br />
4. Empty the fuel tanks or add a fuel stabilizer. Start<br />
the engine and allow it to run until the carburetor<br />
is drained of fuel or the stabilizer has reached the<br />
carburetor.<br />
5. Remove the spark plug and pour about a<br />
tablespoon of engine oil into the cylinder. <strong>turn</strong><br />
over the engine so that the oil is evenly distributed<br />
and then refit the spark plug.<br />
6. Lubricate all grease zerks, joints, and axles.<br />
7. Remove the battery. Clean, charge, and store the<br />
battery in a cool place, but protect it fr<strong>om</strong> direct<br />
cold.<br />
8. Store the machine in a clean, dry place and cover<br />
it for extra protection.<br />
Service<br />
When ordering spare parts, please specify the<br />
purchase year, model, type, and serial number.<br />
Always use genuine <strong>Husqvarna</strong> spare parts.<br />
An annual checkup at an authorized service workshop<br />
is a good way to ensure that the machine performs its<br />
best the following season.<br />
